Series XJ.1I. Erica-Its 



235 Clethraceae Close relations are to be found in the Ericaceoa 

 and in the Ternstroerniaceae ; but in other respects, it is closely allied to the 

 Stachyuraceae and Pentaphylacaceae. 



236 Pirolaceae J) : Intimately related to the Ericaceae. 



237 Lennoacese 1) : Connected with the Ericaceae and Pirolaceao. 



238 Ericaceae 4) ' Certainly referable to the Metachlamydeae ; but, when 

 special attention is given to the stamens sitting not on the corolla but on the 

 disk, one is convinced that there exists an intimate connection between the 

 Ericaceae and choripetalous families. But in the more or less united stamens 

 which are present in some genera of the Ericaceae, the family is related to the 

 Campanulaceae. 



233 Epacridaceae : Near the Ericaceae. 



240 Diapensiacese' : Near the Clethraceae, Pirolaceae and Ericaceae ; and 

 also near the Epacridaceae in the insertion of stamens on the corolla. Another 

 relation exists between the Diapeusiaceae and the Pritnulaceae, as can be seen 

 in a comparison of Scldzocodon and Soldanella. The family is more or less 

 connected with the Polemoniaceae, Loganiaceae and Verbenaceae-Stilbeae. 



Series XL.III. Fritnulales 



241 Theophrastaceae 7) : Approaches the Myrsinaceae, Primulaceae and 

 Sapotaceae. 



242 Myrsinaceae S) : The connection of this family with the Primulaceao 

 is so close that to separate the one from the other is entirely artificial. The 

 family also approaches the Sapotaceae in the floral diagram, but in other 

 respects, it comes near the Corynocarpaceae. 



243 Primulaceae 0) : Related to the Myrsiiiaceae, Plumbagiuaceae and to 

 the Diapensiaceae.
